APPARATUS FOR TREATING GASES.

Application filed February 29, 1924, Serial No. 696,040, and in Germany April 6, 19%.

This invention relates to improvements in or modifications of the apparatus described in my parent specification Ser. No. 644,232, filed June 8, 1923.

h That apparatus was devised for absorption and concentration processes which re quired repeated contact of the gas with the liquid.

According to this invention 1 provide such apparatus with means by which the liquid sprayed into the gas is prevented from again mingling with the liquid which has not been sprayed. e a

By this invention the apparatus described 16 in the parent specification becomes suitable for use in those cases in which the action of the gas upon the liquid is complete at the moment of contact. In such cases a single contact of the gas with the liquid is all that is required and to return the treated liquid into the unsprayed liquid would be detrimental to the economic working of the process.

One means of separating the two liquids 23 consists in forming the gas chamber with a double wall and providing in the inner wall elongated spaces through which the up wardly sprayed liquid passes to flow into a separate collecting chamber.

The invention is illustrated in the accompanying drawing in which, as in the parent specification, 1 and 2 are a series of staggered disks on parallel shafts 3 and 4 which rotate in opposite directions in a chamber formed of housing 9 and bottom 10; liquid passes into the chamber through a pipe 5 and out through outlets 6 and 6'. 7 is the gas inlet and 8 the gas outlet. Q Referring to Figures 1 and 2, the gas 0 chamber is provided with an inner wall formed of inclined slats having between them spaces is while e are collectors for the the lower collecting chamber out of which it passes through outlet 6', the remainder of the sprayed liquid will fall on to the cover a, g

and from that into the collecting chamber.

I claim 1. Apparatus of the class described, comprising a housing, a liquic container within the housing, a spraying device consisting of two shafts carrying disks spaced in parallel relation and partly immersed in the liquid of the container, means for passing gas through the housing above the disks parallel to the shafts and means constructed and ar- 5 ranged to prevent the return of liquid acted upon by the gas to the qontainer.

2. Apparatus of the class described, comprising two shafts in parallel relation, disks mounted on the shafts in staggered relation relatively to each other, a liquid container for maintaining the disks partly immersed,

a housing defining a gas space above the disks and means constructed and arranged to prevent return of liquid acted upon by gas in the gas space, to the container.

3. Apparatus according to claim 1 in which the said last mentioned means are elements defining collecting surfaces so disposed as to conduct sprayed liquid away from the container.

In testimony where I have hereunto set my hand.
